@anom2002 , Welcome to Microsoft Q&A, Please refer to the following steps to write the code to get the wanted call numbers

First, We could use regex to get the number string and alpha string from the source string.

Second, We could get 5 random number from the string 0123456789.

Third, Please insert . to the number.

Fourth, We could get 3 random character from the string 'abcdefghijklmnopqrstuvwxyz' and upper the characters.

Finally, We can use Stringbuilder get the result you want.

Here is a code example you could refer to.
